HIMARS is a transformational 24 hour, ground-based, responsive General Support / General Support-Reinforcing (GS/GSR) precision indirect fire support system which accurately engage targets at long ranges (60+ Km) with high volumes of lethal fire under all weather conditions throughout all phases of combat operations ashore. HIMARS is C-130 and amphibious transportable and with precision fires, supports both irregular and traditional warfare. One HIMARS system is defined as one launcher, two resupply vehicles / trailers and munitions.
The High Mobility Artillery Rocket System (HIMARS) TD will provide a lightweight, C–130 transportable version of the M–270 multiple launch rocket system (MLRS) launcher. Mounted on a 5–ton family of medium tactical vehicles (FMTV) truck chassis, it will fire any rocket or missile in the MLRS family of munitions [MFOM]. The HIMARS launchers will some commonality with its older and heavier tracked cousins, the M270 and M270A1 launcher systems. The HIMARS design concept will include the familiar launcher module, fire control, and digital command and control systems, and a self-reload capability. The HIMARS uses the same command, control, and communications, as well as the same crew, as the MLRS launcher but carries only one rocket or missile pod. It will roll on and off a C–130 transport aircraft and, when carried with a combat load, will be ready to operate within 15 minutes of landing. The HIMARS will fire either six MLRS rockets or one Army Tactical Missile. Because of the lighter weight of using one pod rather than two, it will have a faster time, compared to the current M270, from the point the fire mission is received to the actual munition firing.
The Expeditionary Fire Support System (EFSS) will be the final system of the land-based fire support triad that includes the LW 155 and HIMARS. It is designated to accompany the MAGTF in any expeditionary mode of operations. It will be the primary indirect fire support system for the vertical assault element of the ship-to-objective maneuver (STOM) force. The EFSS shall be capable of 110 nautical mile lift internal to the CH-53E aircraft. The Expeditionary Fire Support System (EFSS) is a fire support system that is designated to accompany the MAGTF in any expeditionary mode of operations.
The MBC automates technical Mortar fire direction and replace the M16 and M19 plotting boards as the primary means of computing 60mm and 81mm mortar firing data. The MBC system consists of a ruggedized handheld device utilizing the latest Windows based operating system to host the Mortar Ballistic Kernel software. This stand-alone system will be fielded to 60mm mortar sections at the infantry company level, and 81mm mortars at the infantry battalion.
The LW155 is the world's first 155mm howitzer with a flyweight of less than 9800 pounds with digital fire control. Designed as artillery support for the Marine Corps and Army Light Forces, the LW155 is air transportable by medium or heavy lift helicopters, the V-22 tilt rotor aircraft, and other tactical transport aircraft. The LW155 offers greater ground mobility and improved reaction times, compared with the greater than 16,000 pound M198 Howitzer it is designed to replace. It also offers significant advantages in the areas of automatic breech opening and primer feed, and crew ergonomics.
The M198 Howitzer provides the user with a towed system that is air transportable, has high reliability and availability while greatly increasing the effective range of towed weaponry. It provides significant improvements in lethality, range, reliability, availability, and rapid emplacement and movement over its predecessor, the M114A1, which was fielded in World War II. The M198 is air transportable by transport aircraft and the CH47C Helicopter. The weapon is designed for use with new ammunition, such as the Copperhead and rocket assisted projectiles, as well as other 155mm standard projectiles and propelling charges. The gun/ammo system complies with the quadrilateral (US, FRG, UK, Italy) ballistic standardization agreements. en rotated 180 degrees and it should be noted how far the reticle in the telescope has moved up or down from its original position.
The aiming circle is used to measure azimuth and elevation angles of a ground or aerial target with respect to a preselected base line.
The M252 81mm Mortar System was developed under a co-developement agreement with the United Kingdom to replace the M29A1 Mortar. A Blast Attenuation Device (BAD) is attached to the muzzle of the cannon assembly to reduce the blast effects on the mortar crew. The M252 is ideally suited to support airborne, air assault, mountain and light infantry units.

The M252 Mortar System consists of the following major components:
- M253 Cannon Assembly (35 lbs)
- M177 Bipod Assembly (27 lbs)
- M3A1 Baseplate (25.5 lbs)
Features: The M252 81mm Medium Extended Range Mortar is a crew-served, medium weight mortar which is highly accurate and provides for a greater range (4,500 meters to 5,650 meters) and lethality than the previous 81mm mortar. The cannon has a crew-removable breech plug and firing pin. The muzzle end has a short tapered lead-in which acts as a blast attenuator device. The breech end is finned for better cooling. This mortar also uses the standard M64 mortar sight of the 60mm mortar, M224.
Background: This mortar replaced the previous Marine Corps 81mm mortar in 1986. The M252 is an adaptation of the standard British 81mm mortar developed in the 1970s. It is mostly commonly found in the mortar platoon of an infantry battalion.
The M224 60mm LWCMS is ideally suited to support airborne, air assault, mountain, ranger, Special Operations Forces and light infantry units. The M224 can be drop fired (conventional mode) or trigger fired (conventional or hand-held mode). A lightweight auxiliary baseplate is used when firing the mortar in the hand-held mode.

The M224 Mortar System consists of the following major components:
- M225 Cannon Assembly (14.4 lbs)
- M170 Bipod Assembly (15.2 lbs)
- M7 Baseplate (14.4 lbs)
- M8 Auxiliary Baseplate (3.6 lbs)
Mission: To provide the company commander with an indirect-fire weapon.
Features: The M224 60mm Lightweight Mortar is a smooth bore, muzzle loading, high-angle-of-fire weapon. The cannon assembly is composed of the barrel, combination base cap, and firing mechanism. The mount consists of a bipod and a base plate which is provided with screw type elevating and traversing mechanisms to elevate/traverse the mortar. The M64 sight unit is attached to the bipod mount via a standard dovetail. An additional short range sight is attached to the base of the cannon tube for firing the mortar on the move and during assaults. It has a spring-type shock absorber to absorb the shock of recoil in firing.
Background: The M224 replaced the older (WWII era) M2 and M19, 60mm Mortars. These weapons only possessed 2,200 yards of effective range. The M224 was designed to fire all types of the older ammunition, but its primary rounds are of the newer, longer-range type.
